Take-home pay only tells part of the story. Mississippi has a cost of living index of 83 while Wyoming is at 94 (national average = 100).
The cost of living gap is moderate. After adjustment, $100K has purchasing power of $90,512 in Mississippi vs $84,176 in Wyoming. However, Mississippi actually provides better purchasing power despite Wyoming’s take-home advantage.
For a single earner at $100K filing jointly, take-home becomes $80,710 in Mississippi and $84,710 in Wyoming \u2014 a difference of $4,000. The gap remains similar regardless of filing status.
On paper, moving from Mississippi to Wyoming would save $4,000/year on a $100K salary, or $20,000 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
The $4,000/year savings is meaningful but probably not enough to justify a move on its own. However, combined with other factors like career growth, lifestyle preferences, or family proximity, it could tip the scale.
